ISO far-infrared observations of rich galaxy clusters. III. Abell 2029, Abell 2052, Abell 2142

Abstract

A sample of five rich galaxy clusters has been mapped by ISO at 60 mu m, 100 mu m, 135 mu m, and 200 mu m using the PHT-C camera. In previous papers Abell 2670 and Sérsic 159-03 were discussed. Here we present the results for Abell 2029, Abell 2052, and Abell 2142. The conclusion of the survey is that the relatively small fields (~60 square arc minutes) are structured with filaments or superpositions of point sources. In some cases point sources (~ 0.1 Jy) can be identified with cluster galaxies. An attempt to demonstrate infrared emission from dust in the cooling flows (due to star formation) was inconclusive. Based on observations with ISO, an ESA project with instruments founded by ESA member states (especially the PI countries: France, Germany, the Netherlands, and the United Kingdom) and with the participation of ISAS and NASA}
